MEANS FOR MOISTENING WARPS DURING WEAVING.

Application filed. January 10, 1924. Serial No. 685,392.

To all whom it may concern:

Be it known that I, CniARLEs FREDERIGK JONES, a subject of the King of Great Britain and Ireland, and resident of Newton Heath, hlanchester, in the county of Lancaster, llngland, have invented certain Im provements in Means for Moistening arps During eaving, of which the following is a specification.

This invention relates to improvements in means for moistening warps in looms during weaving and has reference to the class of device by which the moisture is applied to the warp between the healds and back rest of the loom. My invention is designed to impart the necessary amount of moisture to the warp threads by the direct contact and pressure of a damping member brorght intermittently against the threads, without materially adding humidity to the atn'iosphere of the weaving shed, the amountof moisture so applied being regulatable by varying the pressure and period of contact of the aforesaid damping member.

My invention consists essentially in a damping member reciprocable towards and from the warp or oscillatable about an axis, means for supplying water thereto, means for effecting the reciprocation or oscillation of the member and means to determine its period and pressure of contact with the warp threads My invention will be fully described with reference to the accompanying drawings in which Fig. 1, is a partial side elevation from the inside of so much of a loom frame as is necessary to show the application of my invention to a loom,

Fig. 2, sectional front elevation of same looking towards the rear of the loom,

Fig. 3, longitudinal section of the damping member and i Fig. -il-, transverse section of same.

With the aforesaid objects in view and in a form of my invention I arrange across the loom frame (6 at a position between the healds and back rest Z) a horizontal pipe or conduit 0 conveniently mounted in bearings (Z carried by the side frames of the loom. A convenient arrangement of bearings is to form them in the rear ends of slotted arms 6 each secured by a bolt 7 to a verticallyslotted bracket 9 secured to the frame side of the loom by a bolt 7t so that the bearings and the pipe 0 can be conveniently adjusted horizontally and vertically to arrange the damping member in the required position. The pipe or conduit 0 is provided with a suitable number of perforations i at one side, is closed at one end at and open at the other 7.: to the source of water supply which latter preferably consists of a closed inverted water bottle or other vessol m arranged and supported in any suitable way as by a. stopper it carried by a bracket 0 to which it is secured by a setscrew 1). The water vessel is removably connected to a flexible or other pipe 9 which is, in turn, suitably coupled to the pipe (,1. The latter is provided at its perforated side with a box-like chamber 0 substantially cor-- responding in length to the width of the warp in which is placed a bedding of felt or like porous material 5-. The box is sufliciently deep to support and hold a remov able bar I? of wood'or other suitable material covered with a suitable porous or absorbent fabric a constituting that part of the warp-damping member which comes in contact with the warp o. The pipe 0 with its damping member is oscillated about its own axis by any suitable means to cause the fabric uto intermittently contact with and impart moisture to the warp threads, the damping member being shown out of contact with the warp in full lines in Figs. 1 and 2 and by the broken line circle in Fig. 1, in contact with the warp. One way of effecting the aforesaid movement of the damping member is to couple one end of an adjustable flexible strap or band w to the pipe member 0 and the other end to an arm at connected to the strap 1 of an eccentric 2 fixed on the tappet shaft 3- of the loom. This flexible strap is arranged to pull against the influence of a spring in such away that the pressure of the spring could be increased or decreased so as to determine the pressure to be exerted on the warp threads by the damping member and likewise its period of contact therewith. In the drawings I have shown the employment of a tension spring l connected by one end to the pipe 0 and at the other end to a bracket or arm 5 loosely pivoted on a stud 6 and pressed towards the fixed end of stud by a small coil spring so as to keep the other end of the arm 5 in contact with a pin 7, through the agency of a number of holes 8. By drawing the arm 5 along the stud. 6 to disengage its upper end from the pin 7, such arm can be turned about the stud (3 and be re-engaged with the stud again to give any required tension that may be required to the spring 4.

The water supply to the perforated pipe 0 may be effected from an open vessel or direct from a water service pipe.

In action the water from the source of supply passes into the tube 0 through the holes in the latter to the absorbent material 8 and is, in turn, absorbed from the latter by the fabric a on the damping member. As a rule the fabric on the damping member may be previously soaked in water before the apparatus is put into use so as not to wait until the water from the source of supply soaks through it. When the loom is at work the damping member is made to alternately touch the warp threads and recede from them at a rapid rate with a semi-rotary reciprocating motion, the amount of moisture imparted to the warp threads by the damping member being regulated by the length of time such member is allowed to rest on the threads at each contact and'by the amount of pressure given by the member upon the warp threads to slightly depress them. This regulation is effected by means of the adjustable flexible band or strap by the tightening or slackening of the coiled spring or by the vertical adjustment of the bearing bracket. The dwell on the warp threads is also partly dependent upon the adjustment of the flexible band which may be arranged to be slightly slack for the return motion. lVhen the loom is stopped the damping member is in its top position and well out of the way so leaving ample room under the tube and member to enable the weaver to piece up broken ends in that part of the warp without inconvenience. The damping member does not make contact with the warp whilst the loom is stopped so that excessive moisture at one point of the Warp and any danger of discoloration of the yarn by lengthened contact is avoided.

Instead of the damping member being) oscillated about an axis it may be reciprocated towards and from the warp by any suitable means such for instance by mounting the damping member in bearing brackets actuated by cams or other means. Such bearings may be resilient and adjustable to enable the necessary elastic pressure and dwell to be regulated as in the ar rangement previously described.

hat I claim as m invention and desire to secure by Letters latent is:-

1. A warp moistening apparatus, com prising a stationary support, a water supply pipe mounted to rock in the support and having perforations in one side, a moistening pad secured at one side of the pipe over its perforations, a spring which moves the pipe axially in one direction to press the pad on the threads, and means for moving the pipe axially in the reverse direction at intervals to relieve the threads from the pressure of the pad.

2. A warp moistening apparatus as set forth in claim 1, the said support consisting oftwo slotted arms arranged crosswise of each other and enabling the position of the pipe to be adjusted horizontally and vertically.

3. In a warp damping member or apparatus comprising a perforated pipe mounted in bearings at the rear of the loom and arranged transversely of the warp, a water supply pipe connected to the perforated pipe and to an inverted or ordinary water supply vessel, a chamber forming part of or connected to the pipe to receive a felt pad and a wooden or other suitable rod covered with porous material, an adjustable band or strap connected by one end to the perforated pipe and by the other to a rod connected to an eccentric strap and an eccentric or other means for moving the damping member in one direction and an adjustable spring for imparting motion in the opposite. direction.

a. In a warp damping apparatus having a springas claimed in claim 1, the means for adjusting the tension of the spring consisting of a pivoted lever coupled to one end of the spring by one arm and provided in the other arm with a number of holes (:0- acting with a fixed pin.

In testimonywhereof I have hereunto set my hand.
